Retail/food service if I remember correctly. Zach also was a drop out but got a GED. They're permanent positions, he just turned them into short term ones.but those aren't real jobs- if they're always short term it's hardly like he's working. I mean a real job. or did he have some kind of actual useful career?
Edit: possibly construction too. Lived in an apartment for free because his then boss owned it. That arrangement lasted 3 weeks before being fired.
